While it remains unclear how exactly the studio uses hashes for NFT minting, the total trading volume with these tokens on OpenSea hit a whopping 616 ETH (~$2.3 million).

The studio already issued two collections called $HASH and $London. The last one is dedicated to Ethereum's notorious London hard fork, which introduced the EIP-1559 mechanism, a concept of burning a portion of the gas fee for ETH transactions.
